I tried to find TCN by "show spanning-tree detail" but i don't find any TCN happen.
What else should i check ?
The mac-move feature doesn't shows any entries. I expected to see many entries, because the Host Learning queue still shows an 1 hour average of 3819!
Regarding SPAN i don't have a SPAN Destination port at the moment.
Another question: There are two Core-Switches and some distribution switches are connected to each of the Core-Switch. On the trunks between the core-Switches and Distribution-Switches there are only some vlan allowed via "trunk allowed vlan".
Furthermore i can see that there are different spanning-tree root bridges for the same VLAN, e.g. if a VLAN is not allowed to a Distribution Switch, this Switch will be the root instead of the desired first Core-Switch. Is this a normal behaviour?
Must the trunk allowed configuration match on the link between core- and Distribution Switch?

Windows search filter host high CPU
Guys
I've read through many threads on this problem where Windows search filter host high CPU is staying at over 50% constantly. Not one thread points to a solution. Does anybody know how to fix this apart from disabling the service?

Not one thread points to a solution, IMHO there's a lot of factors to consider. Hardware issue, components or chips inside your processor could be faulty. Motherboard issues could
lead also a load on CPU.
CPU Fan, Casing ventilation, processor heat sink etc..
Software issue, spyware, malware or virus that goes undetected causing a load or spike on your processor.
Application software etc... countless possibilities.
- does it happened the moment you configure the server? or the first time you turn on your server?
- any recent changes on your server? (hardware or software installed)
run sfc /scannow check for any file system corruption

CF 10 sp 12 Enterprise high CPU usage hangs services, 2012 server on 2012 Hyper-V host
The last 2 days - my [removed link] CF site has suffered from high CPU usage (on and off) that stops functionality.
This will last several minutes then suddenly the high usage stops a few minute later the high cpu usage starts again.
I don't have any scheduled processes allowed to run.
Restarting the coldfusion service during a high CPS incident - the cpu usage just picks up where it left off when restarted.
I have assigned 4 CPUs (normal) or 8CPUs (as a test) to the VM and I get the same high CPU then low usage. This is a fresh install several months ago on a new VM.
I'd like some Adobe support on this issue but can't seem to find the contact phone number.
This series of high and low cpu usage first started Monday AM about midnight until 7:00 AM Tuesday was quiet and Wednesday this AM I'm having the same issues.
Ideas?
Update: While waiting for this to post - the high CPU usage started again and this time I stopped and restarted the Jetty service ... and the CPU usage went away...
Update: the high cpu started again and a restart of the jetty service didn't help --- neither did the .net service restart... the cf10 application service did stop the high usage...

High CPU usage because of Biztalk Server
How do you prevent Biztalk Server from causing the CPU to go high?
ChristianeHi Christiane,
To prevent
BizTalk Server from causing high CPU, identify the root cause and solve it.
Analyze the performance counters, as
Tomasso suggested start with
PAL tool and analyze its report.
MessageBox viewer should also give you indicators with critical errors.
More often it’s due to tracking. Check the level of tracking enabled. Make
sure the SQL Agent jobs are all working as expected to clean up the BizTalk tables.
Following article shall help you:

High CPU usage by Service Host & Services and Controller app
Hi All,
My CPU is running at a consistent 98-99% within moments after booting my machine. I have uploaded a ~30s ETL capture here:
hxxps://www.dropbox.com/s/xznhkdyo5p2p7rn/highcpu.07-03-2014.10-46-16.zip
I've been digging around, but I can't seem to find what the cause of this high CPU usage is. It appears to be affecting the explorer service as well as Chrome. CPU usage does NOT go down if I kill all chrome processes however.
Any insight would be wonderful.Hi,
According to your screenshot, it seems this is not related a particular service, it just like a memory leak issue.
Can you check the event viewer to see if there is some error record?
Or you can check if this issue happens in Clean Boot mode, this would eliminate software conflict:

Attn: ALL APPLE PORTABLE OWNERS -MacBook Pro, MacBook Air, Mac mini slowdown kernel / high CPU use problem and solution.
YOU COULD FRY YOUR COMPUTER IF YOU DO NOT FIX THIS PROBLEM SO PLEASE READ THIS ENTIRE MESSAGE!
YOUR MAC WILL THANK YOU
Hey all.
Like many of you I've got a newer Apple portable which slows down to an unusable level for an unknown reason. In my case a 13" mid 2009 Intel MacBook Pro Core 2 duo laptop. After many failed attempts to figure out what this nutty problem is I have discovered the problem, the solution and I have solved this for my own MacBook Pro. Since this fix it has been working immediately and consistently -without issue
I am sharing this with you in hopes that you to can fix your Apple portable yourself or so you know what to tell the Apple techs so they can quickly fix your Mac from this wacky and unfortunate kernel CPU hogging problem.
User Software Symptoms :
Your Apple portable computer periodically for an unknown reason slows down making everything frustratingly slow. This happens even when running previous apps that were never a problem; things that your Mac should be able to handle easily but for some reason now it can't.
Slowdown most often happens during high CPU use such as gaming, video playback/editing, etc. or when running multiple apps (even non CPU intensive apps) at the same time.
Possible Hardware Symptoms:
Your computer is making more noise than it did previously.
Your computer occasionally makes more noise but then gets quieter.
Your computer is always extremely quiet (too quiet) even during high CPU apps -worst case scenario.
It feels hotter than it normally does. Test: After several minutes of the slowness/high kernel CPU touch the computer to feel if it's hotter than normal.
Looking at Activity Monitor (in the Utilities folder) shows the kernel_task is going bonkers eating up CPU but you have no idea why.
After trying many different things to solve this problem such as :
PR ram reset, SMC reset, fresh OS install of 10.5 and 10.6 on external hard-drives, calling and speaking to various Apple tech people who had no ideas/solutions, etc. I had no luck.
Btw, if you're having the symptoms I've decscribed above I would not run the Apple Hardware check (read below as to why). You could fry your Mac!
After much testing I found the problem :
It is my belief that "recent" Apple portable computers are using low quality internal fans which soon stop working!
Fail time period seems to be about 1.0 years to 2.5 years of use but this fail rate could vary depending on use.
First noticeable symptoms (depending on what you notice) could be computer slowdown or your fan is making more noise than it normally does. This is your fan's lubrication slowly eroding making your fan spin slower and less smooth resulting in the louder noise and slower rpm spin speed. The slower fan spin speed means less cooling is happening for your computer. The effect on your computer is that the CPU and other chips are heating up! Overheating to be more specific. When your computer's chips overheat they get wonky and screw things up. Most often this seems to have the effect of making the kernel hog CPU resulting in a frustratingly slow user experience! Heat kills computer chips and it is extremely bad for them. Extreme overheat or repeated overheating has been said to shorten the life of computer chips or in extreme cases even fry them completely!
The longer this goes on without being fixed your fan loses more lubrication and spins slower and slower cooling lesser and lesser resulting in your CPU heating up more and more possibly shortening the life of your Mac! Eventually your fan will stop completely and you could fry your chips! My fan stopped completely and my MBP was running very quietly, too quietly. Luckily I did not fry my chips because I was avoiding using high CPU apps because I knew something was wrong due to the massive slow down and wonkiness when I'd run them.
Side Note:I'm a bit concerned about all those Mac mini servers which may be using the same defective low quality fans which cannot be easily serviced by their owners as they are co-located in some server facility. One positive thing is those facilities are usually well airconditioned keeping temps low.
I suggest you do not run the Apple hardware test if you suspect your computer is overheating because the hardware test can seriously heat up your Mac! I tried running this test and my Mac got so hot I had to shut it down forcefully and I was concerned I damaged the chips. If you want to run the Apple hardware check make sure your CPU temperature is ok and that your fan works well before you run the test.
IF YOU DON'T FIX THIS PROBLEM YOU COULD FRY YOUR COMPUTER DUE TO HEAT DAMAGE!
DO NOT IGNORE THIS PROBLEM YOUR MACS LIFE MAY DEPEND ON IT!
First you need to properly diagnose this problem and see if your CPU is getting to hot and you need to see if your fans are spinning at high rpms giving proper cooling, or if they are spinning at low rpms when running high intensive apps as your CPU temp increases.
TEST IF YOUR FAN(s) IS WORKING CORRECTLY :
Unfortunately Apple does not include CPU temperature reading software nor fan rpm speed software that I am aware of.
However, There are two free ways that I know of to check your CPU tempurature and your fan speed :
One app shows fan speed, and CPU heat, etc.
One app shows fan speed, CPU heat and allows you to adjust your fan speed settings.
One app is a dashboard widget, the other is a system preference.
I suggest you download both of these to check your computer statistics.
http://www.eidac.de/?p=134
http://www.islayer.com/apps/istatpro/
http://fan-control.en.softonic.com/mac
I am not exactly sure what proper CPU temperatures are for the different Apple computers and this will change given different CPU loads.
My MBP doesn't seem to function properly with anything around 90 degrees or higher (celcius).
It seems when the fan is operating normally the CPU temp should not stay above 78 degrees even under heavy load, at least with the apps I'm running in the room temperature I'm in.
I can post back later with more specific temps under longer load, etc. but I wanted to get this post up for people to read as soon as possible so they don't fry their Macs.
If a bad fan is your problem :
THERE ARE ONLY TWO SOLUTIONS FOR THIS PROBLEM :
Fix or replace your fan so it cools the CPU and other chips properly.
I fixed my fan myself and I didn't need to buy a new one. Total cost was about $8.00 because I had to buy a #00 sized screwdriver and had it shipped to me. Price includes shipping.
On my mid 2009 model MacBook Pro fixing the fan was incredibly easy :
Before I started doing this I wasn't 100% this was the problem so I decided to try to fix my fan instead of ordering a new one and replacing it. As it turns out I didn't need a new fan, I only needed to clean the existing fan and relube it's axl so it could spin easier like when it was new. It also didn't make sense to buy a brand new fan from an Apple authorized parts reseller selling me the same low quality fan for $49.00 which would probably fail in 2 years again. Prices for new comparable fans from different manufactures range from about $15.00 USD + shipping to around $49.00 USD + shipping depending on where you order them from and what brand you get.
How to fix / replace your internal fan on a mid 2009 MacBook Pro :
Please note : I am not a hardware technician, nor expert. If you decide to fix your Mac yourself you do so at your own risk through no fault of my own. Prior to opening up your Mac you should google around and learn how to do it correctly and safely so you won't damage your Mac. For example, it is possible for you to damage your Mac by static electricity from your body. To avoid this I believe proper procedure is that you wear a 'ground strap' (around your wrist) which you clip to your Mac's metal body so your body will not excude a charge into your Mac. I believe the idea here is to keep your body's charge level and your Mac's similar. Since I do not have a ground strap and fixing/replacing the fan doesn't require touching any chips I did not wear a ground strap during my fan fix. What I did was periodically repeatedly touch the metal case of my MBP hoping that would be enough and it was. Avoid unecessary actions that can build up a static charge in you. Once I started the repair I did not walk around the room building up an electrical charge in my body. Walking on carpet can often build up a large charge in us so it is better to be avoided while working on your Mac. Certain clothing can build up static charges. Combing hair, etc. If you need to get up from your repair when you come back make sure you first touch the Mac's metal case and not anything inside.
Now that we're done with the scary paranoia, below you will find some instructions on how I fixed my MBP's internal fan
Before you begin:
Check out someone's video (not mine) on how to remove / replace the fan (but not take it apart and repair it):
http://www.youtube.com/watch?v=AghE9newvbs
Check out someone's web page (not mine) on how to replace the fan in a mid 2009 MacBook Pro:
http://www.ifixit.com/Guide/Installing-MacBook-Pro-13-Inch-Unibody-Mid-2009-Fan/ 1338/1
How to repair your mid 2009 MacBook Pro fan:
Make sure you are in a 'secure' environment. No pets, no kids running around, no drinks near the Mac, etc.
Make sure your computer is unplugged from it's power supply and turned off. NOT slept. Totally off / powered down.
1. Get a size #00 phillips screwdriver (Hobby store, Radioshack, Amazon).
2. Open up your MBP by unscrewing the bottom (yes flip it over so it's resting upsidedown). Note where each screw goes because some are different lengths. I placed each one around my MBP where they go, insuring I know their order (don't jumble them up). Note which direction your MBP is facing when it's upside down so if you spin it around while working on it you still know where the screws go.
2b. Some recommend removing the MBP's battery but I didn't do this step. You probably should, just to be safe. Follow the online instructions from the web page I listed about disconnecting the battery.
3. Unscrew the fan's 3 holding screws.
4. Unplug the fan's electrical connection (lift it straight up off the board). If you need to you can try to pry it up while you lift with a non metal/non electrical conductive object like a spudger if you have one or -perhaps a pen cap. Before you remove it, look closely at how it's attached so when you put it back on you won't wonder if you're doing it correctly. There's only one way it can go because it cannot fit 'the wrong way' but looking at it closely will make you feel more confident popping it back on when the time comes.
5. Remove the fan - it easily lifts out.
6. Take the fan apart by unscrewing it's one screw then unlatching the plastic clips which hold it together.
7. Seperate the fan blades from the housing. Lift the fan blades off of the fan housing by pulling it straight out away from the housing.
8. Clean off the dust that's gathered. A can of compressed air helps here (I didn't have one). I used a little brush from my electric shaver kit which worked well. Once you've removed all the dust from the fan and surrounding areas proceed to the next step.
9. Reapply new lubrication. You need less than 1 drop. Be sure it covers the entire fan blade axl as this is what needs to be well lubricated. Make sure there isn't excess oil that will fly around when the axl/fan spins at high rpms. I used the only oil I had which was olive oil (for cooking!) but I do not suggest this. At the time I was doing this I didn't know my fan was the problem so I wasn't even sure I was going to relube it. You should probably use something more appropriate perhaps like 3 in 1 oil. A good idea would be to call the manufatures of these little fans and ask them. Maybe a hobby store knows of good lubricants for these purposes?
DO NOT use things like WD 40 as it's not a long term lubricant or so I've read.
10. Once your fan is now clean and oiled (make sure there isn't too much oil) reassmble the fan.
Push the fan blades/axl back into the housing shaft. Give it a few spins with your finger.
Screw together the fan housing then reclip the clips.
11. Place the now reassembled fan back into your Mac and screw it in place (3 screws).
12. Reattach the fan's electrical wiring by gently pushing it into place. Make sure you've got the right end facing down before you push it in place.
13. Once your Mac's internals are clean and reassembled, place the rear cover back on your Mac and screw it in place.
14. Double check you didn't forget anything like screws, tools, etc.
15. Boot up your Mac and monitor the temperature and fan speed using those programs.
Compare the previous temps/fan speed to the current temp/fan speed.
Run a high CPU intensive app where your computer has been slowing down.
You should now have a happy Mac
If you have this problem and this solution fixed it for you please post in this thread letting me and everyone else know!
Hope that helps.Thanks for your lengthy reminder dude, I have a similar Mac with yours. I suspect its a software fault because it happens after I upgraded to Lion, 10.7.2.

High CPU usage warning, how to fix??
Hey all -- First off, my laptop is brand new, and it is a Satellite C875D - S7120, using Windows 8. So far so good, everything seems to be fine EXCEPT...I am an artist and I have a couple of 3D programs installed. But every time I try to use them I get a "High CPU usage" error, like the art program is taxing the computer too much. I'm not a gamer... it seems to me that simple 3D imagery wouldn't cause this. But how do I fix it? I'm not that computer savvy...I've heard about registry problems but wouldn't have a blind clue how to get in there and fix anything... PLEASE ADVISE! -- Thanks in advance, Krystal
Ahh, Jerry, you are a friend in (my) need...will pounce on this ASAP! Twiddling around with this new device of mine is a challenge but also a learning experience. Probably the most important thing right now is NOT getting it 3D-ready but instead, teaching myself how to manage the innards...
Moki, someone on deviantART who is very skilled w/ Blender has said that they don't like the latest version because it is quite different from earlier versions. I haven't done anything with it in yonks, so once I get into it again, that shouldn't bother me. But it's true, "improvements" always seem to just weigh a program (any program) down instead of making it easier to use. That was why I have preferred older versions of some things instead of what's new out there, as the older ones are slimmer and not such resource hogs...
Disabling RayTracing...hmm! I shall definitely do that...plus try all the many other tips! *bookmarks page* I could even try that on this old XP, since I have Blender installed here also.
So if Toshiba is strong enough to handle graphics projects way beyond my modest little ventures (I doubt I'll be making movies anytime soon!), I ought to be able to get this puppy set up for it without too much trouble....let us hope.... -

If you set the logging level to notice-5 or higher, the SCM utilization may peak at approximately 90 percent because each connection generates a redundant index mismatch log entry. For example:
AUG 7 14:12:15 3/1 1124272 SLR-5: Rejected. Redundant global rule index (7) not found.
This might probably the reason for the High CPU utilization.
The CSS 11800 with CSS8-SCM Redundant System Control Module (SCM) is designated for end of sales.
The recommended replacements for the Cisco CSS 11800 include the Cisco CSS 11500 Series Content Services Switch or the Content Switching Module (CSM)an integrated services module for the Cisco Catalyst. 6500 Series Switch and the Cisco 7600 Internet Router. -

I want exact troubleshooting.
(1) Steps to follow.
(2) Required configuration
(3) Any good suggestions
(4) Any Tool to troubleshoot.
Suggestions are welcomeHello,
NMS is probably not the right community to t/s this. You probably want to move this to Security group (Security > Firewalling).
In the meanwhile, i have some details to share for you to check, though i am not a security/ASA expert.
The Dispatch Unit is a process that continually runs on single-core ASAs (models 5505, 5510, 5520, 5540, 5550). The Dispatch Unit takes packets off of the interface driver and passes them to the ASA SoftNP for further processing; it also performs the reverse process.
To determine if the Dispatch Unit process is utilizing the majority of the CPU time, use the command show cpu usage and show process cpu-usage sorted non-zero
show cpu usage (and show cpu usage detail) will show the usage of the ASA CPU cores:
ASA# show cpu usage
CPU utilization for 5 seconds = 0%; 1 minute: 1%; 5 minutes: 0%
show process cpu-usage sorted non-zero will display a sorted list of processes that are using the CPU usage.
In the example below, the Dispatch Unit process has used 50 percent of the CPU for the last 5 seconds:
ASA# show process cpu-usage sorted non-zero
0x0827e731 0xc85c5bf4 50.5% 50.4% 50.3% Dispatch Unit
0x0888d0dc 0xc85b76b4 2.3% 5.3% 5.5% esw_stats
0x090b0155 0xc859ae40 1.5% 0.4% 0.1% ssh
0x0878d2de 0xc85b22c8 0.1% 0.1% 0.1% ARP Thread
0x088c8ad5 0xc85b1268 0.1% 0.1% 0.1% MFIB
0x08cdd5cc 0xc85b4fd0 0.1% 0.1% 0.1% update_cpu_usage
If Dispatch Unit is listed as a top consumer of CPU usage, then use this document to narrow down what might be causing the Dispatch Unit process to be so active.
Most cases of high CPU utilization occur because the Dispatch Unit process is high. Common causes of high utilization include:
Oversubscription
Routing loops
Host with a high number of connections
Excessive system logs
Unequal traffic distribution
More t/s details can be shared by the ASA members from the community.

We recently configured a stack of four 48 port 3750-x switches . We are noticing high CPU usage. "Hulc LED process" seems pretty high.
This has coincided with VMware servers getting slow and non-responsive at times, perhaps a coincidence, not sure.
Below I provided some outputs that might help to diagnose it
Thanks

I was aware of the many ACLs however we used to have the same ACLs in a previous 3750G stack about 2 weeks ago and we never had this issue. I agree I need to optimize them and do somehing because it is reaching its max before the CPU starts processing them but I am not certain this is what is causing the issue.
Nikolay,
I am trying to understand "interrupts" with the analysis of the outputs I posted. Here is another output deom the link you provided. Please post your thoughts if you can.
This switch also serves as a gateway(L3 role) for many systems. Would it make sense to offload that responsability from this switch and let an actual router do it?
Thanks
Johnny

Firefox very slow and high cpu usage!! (all other browse slow too)
Sorry, I asked it in 'Newbie Corner' , but still no resolved. so I asked here.
Hi all,
when i open a website just as www.sohu.com, my firefox (3.0.3) hang on, then display the web page very slow , and slow scroll , firefox cpu usage nearly about 100.
I tried some sloution,like modify /etc/enviroment to set MOD_DISABLE_PANGO=1,
or disable 'tell me if a web site ...' in firefox security option.
but still slow.
some people says it's must because flash or some js.
but when i try it in windows or ubuntu, it very fast, not like in archlinux.
so i think some thing wrong in archlinux. I need your helps.
thank you.
p.s.
1. pacman is very fast (the speed of wget about 400k/s)
2. gnome web browser like firefox , slow and high cpu.
3. the list of output of 'locale' about 11 lines.
4. i have already set host name like wiki says.
5. the system is a new systemhttp://wiki.archlinux.org/index.php/For … Bumping.27 ??

You are having a bridging loop. Check the devices connected on gi5/4 and gi2/5
Show cdp neig gi5/4 deta
Show cdp neig gi2/5 deta
Once you know what our neighbors are, go on our neighbors and issue the following multiple times:
show mac-address address 00:0C:29:60:42:BF.
You have vmware and dell vendors involved. Check for nic teaming on the vmware side.
You should see this MAC being learned on the interface connected to gi5/4 or gi 2/5 sometimes, and another
interface the other times. Once you know which ports these respective switches are learning the MAC from, issue
the 'show cdp neighbor' and do this again.
Eventually, you should get to a pair of ports that aren't connected to a switch, and only have this MAC learned.
Once you have these ports, you should be able to figure out what kind of devices these are, and why they are sourcing
traffic from the same MAC.
You can enable to debug command to identity the top interfaces that send traffic/packets for CPU processing.

Hi,
We have Cisco 4507R-E and we see a high CPU even at nights when there is no much more traffic on the switch.
Here are the some cpu cpmmand outputs.

I cannot find anything about the process K5L3Unicast Adj Tabl on yhe internet.Hi
The platform-process “K5L3Unicast Adj Tabl”, that causes the high CPU usage is a platform-process that is active when a new MAC address has been learned and the adjacency table is rewritten. This takes place when in the switch receives an unknown source MAC address, it’s forwarded to the CPU for MAC address learning.
It could be possible to have a device connected to a switch port sending lots of MAC address randomly and massively forcing the switch to spend all CPU capacity just to process the new MAC addresses.
So next step is check the interface statistics looking for the highest traffic rate. Use this link below in order to troubleshoot this issue and find the top offender interface.

Hope this helps. -
Hi everybody.
I got GETVPN infrastructure, with two keyservers and 32 group members.
Every time the rekey process takes place, all the groupmembers present high cpu usage and the Crypto ACL consumes all of my resources.
I am very lost, because is a pretty straight forward configuration.

Thanks for your adviceHello,
NMS is probably not the right community to t/s this. You probably want to move this to Security group (Security > Firewalling).
In the meanwhile, i have some details to share for you to check, though i am not a security/ASA expert.
The Dispatch Unit is a process that continually runs on single-core ASAs (models 5505, 5510, 5520, 5540, 5550). The Dispatch Unit takes packets off of the interface driver and passes them to the ASA SoftNP for further processing; it also performs the reverse process.
To determine if the Dispatch Unit process is utilizing the majority of the CPU time, use the command show cpu usage and show process cpu-usage sorted non-zero
show cpu usage (and show cpu usage detail) will show the usage of the ASA CPU cores:
ASA# show cpu usage
CPU utilization for 5 seconds = 0%; 1 minute: 1%; 5 minutes: 0%
show process cpu-usage sorted non-zero will display a sorted list of processes that are using the CPU usage.
In the example below, the Dispatch Unit process has used 50 percent of the CPU for the last 5 seconds:
ASA# show process cpu-usage sorted non-zero
0x0827e731 0xc85c5bf4 50.5% 50.4% 50.3% Dispatch Unit
0x0888d0dc 0xc85b76b4 2.3% 5.3% 5.5% esw_stats
0x090b0155 0xc859ae40 1.5% 0.4% 0.1% ssh
0x0878d2de 0xc85b22c8 0.1% 0.1% 0.1% ARP Thread
0x088c8ad5 0xc85b1268 0.1% 0.1% 0.1% MFIB
0x08cdd5cc 0xc85b4fd0 0.1% 0.1% 0.1% update_cpu_usage
If Dispatch Unit is listed as a top consumer of CPU usage, then use this document to narrow down what might be causing the Dispatch Unit process to be so active.
Most cases of high CPU utilization occur because the Dispatch Unit process is high. Common causes of high utilization include:
Oversubscription
Routing loops
Host with a high number of connections
Excessive system logs
Unequal traffic distribution
More t/s details can be shared by the ASA members from the community.

Both of these seem a bit high don't you think?
If you have any idea as to why this is happening. Or is this normal?
ThanksHi,
This could be related to L2 issues like a loop, see that the K2L2 Address Table R process has a target of 2.00% and is currently running at 72.93%, which is way over the expected target, this can be an indication of host/mac flapping issues. Also the host learning queue seems very high and the L2/L3 control.
You can enable mac notification mac move command to see if on the logs are any flapping issues. Also below is a link which is very helpful when dealing with high cpu issues on 4500.
